khan143 on "How to create a custom table in wp, and how to enter the data in that table"

Hi guys.
I am completely new to wordpress. and using it in my first project as a starter.
I have custom html,css template which I have converted to wordpress.
In this template there is a form for front end users which has fields like "Date & Time from", "Date & time to" which is a date & time picker, "Name", "Email", a dropdown list, and "Message" which is a text area and an optional external file attachment option.
Now I want to customise it in wordpress, that when a front end user fills this form then its data should be saved in a custom table in database, and the admin can see, update and delete this data on admin side.
Please if anyone one knows the answer or having plugin then please tell me.
thanks in advance.
